Comment # 1 on bug 1184608 from Stefan Br���ns

Apparently, the automatic dependency generator is not able to generated
provides for "older" API versions supported.

E.g.:

$> rpm -qv --provides mono-core | grep -E 'mscorlib|netstandard'
manual: mono(mscorlib) = 1.0.5000.0
manual: mono(mscorlib) = 2.0.0.0
manual: mono(mscorlib) = 4.0.0.0
auto: mono(mscorlib) = 4.0.0.0
auto: mono(netstandard) = 2.1.0.0

Until the dep generator is able to handle this correctly, adding a manual
provides is probably the way to go.
